Process and deliver touch events

Does not include pointer emulation handling.
Does include partial ownership handling but not the actual processing of
ownership events.

Note: this commit is a retroactive commit extracted from a series of ~50
commits and may thus appear a bit more complicated than what you'd write out
from scratch.

Pointer processing tree is roughly:
- ProcessOtherEvents
  - ProcessTouchEvents
    - DeliverTouchEvents
      - DeliverTouchBeginEvent|DeliverTouchEndEvent|...
        - DeliverOneTouchEvent

Also hooks up the event history playing to the right function now.
